About These Birds
European Roller
The European roller gets its name from the spectacular rolling and tumbling aerial displays performed by males during courtship. It is the only roller species in Europe and one of the continent's most colorful birds. Declining across much of its western range due to agricultural intensification and habitat loss.
Búteo-de-cauda-vermelha
The red-tailed hawk is the most widespread and common hawk in North America. Its screaming cry is so iconic that it is often dubbed over bald eagle footage in films and television. These adaptable raptors thrive in human-altered landscapes and are a familiar sight perched along highways.
